NO NEEDLE VASECTOMY

The “NO NEEDLE” VASECTOMY was introduced in the United States by Dr. Chuck Wilson, a Family Practice physician from Seattle with a special interest in vasectomies in 1999. Rather than using a small needle to inject lidocaine into the skin and next to the vas deferens, a hypo-spray shoots a tiny stream of lidocaine penetrating less than a 1/4 inch into the skin and around the vas deferens tubes. This injection happens in a tenth of a second and is nearly painless. It uses a fraction of the lidocaine compared with typical needle infiltration and appears to provide equal or superior local anesthesia.

Neither the “no scalpel” nor the “no needle” techniques change the need to CONTINUE USING BIRTH CONTROL following the vasectomy procedure until a semen test proves that sterility has been achieved.
